What a coincidence! I have just read an article. Here are some language they recommend to use for designing website
HTML
HTML is the standardized markup language that structures and formats content on the web. Page elements like the titles, headings, text and links are included in the HTML document. It is one of the core technologies in use on the Internet and serves as the backbone of all webpages.
JavaScript
JavaScript is the programming language that brings animation, games, apps, interactivity and other dynamic effects to life. After HTML and CSS, it’s the most ubiquitous of the client-side scripts. Some JavaScript applications can even run without connecting back to a web server, which means they’ll work in a browser with or without an Internet connection.
PHP
Used by 75 percent of all web servers, PHP is a general-purpose server-side scripting language. The chief advantages of PHP are that it is open source, with a huge online community to support it, and that it’s compatible across multiple platforms. PHP is most often used by websites with lower traffic demands.
Python
Python is a general purpose, high-level programming language that puts an emphasis on code readability; for web developers, this means they can do more with fewer lines of code than other popular languages.
Ruby
Ruby is similar to Python in that it was designed to make programming more productive by emphasizing short and simple code that’s concise, consistent and flexible.
Where Ruby differs is in its language or syntax. In Python, there is only one right way to program things, and it’s efficient and fast. In Ruby, there are multiple ways to do the same thing, and some may be faster than others. Which language you use is really a matter of preference.
